We decided to include label inside the focus indicator for radio and checkboxes, because:
The input-box is small, so the visible focus area will be small when only box has border. To increase visibility we should include the label in the focus-outline. See comment from @anderssonsaja .
The focus-area is the same as the click-area. (except description).
Reading on W3 I see that they have focus around label and element: https://www.w3.org/WAI/ARIA/apg/patterns/switch/examples/switch-checkbox/ https://www.w3.org/WAI/ARIA/apg/patterns/checkbox/examples/checkbox/
